Megha-Tropiques is a satellite mission to study the water cycle in the tropical atmosphere in the context of climate change A collaborative effort between Indian Space Research Organisation ( ISRO) and French Centre National d’Etudes Spatiales ( CNES), Megha-Tropiques was successfully deployed into orbit by a PSLV rocket in October 2011.
Megha-Tropiques was initially scrapped in 2003, but later revived in 2004 after India increased its contribution and overall costs were lowered. With the progress made by GEWEX (Global Energy and Water Cycle Experiment), Megha-Tropiques is designed to understand tropical meteorological and climatic processes, by obtaining reliable statistics on the water and energy budget of the tropical atmosphere. Megha-Tropiques complements other data in the current regional monsoon projects such as MAHASRI and the completed GAME project. Megha-Tropiques also seeks to describe the evolution of major tropical weather systems. The focus will be the repetitive measurement of the tropics.
